397929 divided by 78 
Let's see how many times 78 fits into 397929.

On to step 1:
78 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 78

Step 2:
If we divide 39 by 78, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 78

On to step 3:
397 divided by 78 is 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 7 after subtracting 390 from 397.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 78

Let's proceed to step 4:
The number 78 fits into 79 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we take 78 away from 79, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 78

Let's proceed to step 5:
12 divided by 78 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 510.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 78

Going ahead to step 6:
129 divided by 78 is 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 5101.0
Subtract 78 from 129 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
510 divided by 78 is 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 5101.6
If we subtract 468 from 510, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
420 divided by 78 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 5101.65
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
The number 78 fits into 300 3 times, leaving a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 5101.653
Deduct 234 from 300 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
78 goes into 660 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 5101.6538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
When dividing 360 by 78, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 5101.65384
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
When dividing 480 by 78, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 5101.653846
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
The number 78 fits into 120 1 times, leaving a remainder of 42.
The next digit of our result is 1. 
Result so far: 5101.6538461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
78 goes into 420 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 5101.65384615
Deduct 390 from 420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 5101.65384615 with a balance of 3e-08.
